iMPROVED REFRIGERATORFOR. SODA-WATER AND SIRUPS.

Specification forming part of Letters Patent No. 39,052, dated June 30,1863.

.To cir/ZZ whom it may concern.-

Be it known that I, JAMES W. TUF'rs, a resident of Medford, in thecounty of Middlesex and State of Massachusetts, have invented a new anduseful Apparatus for Refrigerating or Cooling Sirups or Sirups andSoda-Water; and I do hereby declare the same to be fully described inthe following specication, and represented in the accompanying drawings,of which-l Figure l is a top view of the apparatus with its coversraised. Fig. 2 is a transverse section of it. Fig. 3 is a longitudinalsection taken through the sirup holders or chambers. Fig. 4 is alongitudinal section taken throu-gh the soda vessel or cylinder.

My invention is a sirup refrigerator or cooler, consisting of a seriesof sirup holders or chambers, an ice-holding chamber, and certainlateral auxiliary chambers leading out of the several sirup-chambers andthrough the ice-holding chamber, the whole being substantially ashereinafter explained.

My invention further consists in an arrangement of two series of siru pchambers or holders, an ice-holdin g chamber, and a soda vessel orcylinder provided with pipes ofinlet and discharge, the whole beingsubstantially as hereinafter described.

In the drawings, A denotes the external case of the apparatus. Withinthe same there is a row or series of deep vertical chambers, a. a a a,which are disposed against another chamber, b, for containing ice.

Extending from the lower part of each of the chambers a., and throughand across the iceholding chamber b, is another auxiliary chamber, c,which opens into its sirup-chamber a by two holes, d e, one of which isclose to the bottom of the chamber c, while the other is close to itstop. As each chamber c is to de cline somewhat in its departure from itschamber a, the upper hole, e, serves to permit the air, which mayaccumulate in the chamber c, t0 escape into and through the chamber a.,during the process of supplying the chamber with sirup or `Whilesupplied therewith. In passing from the chamber o into the chamber c thesirup will tlow into the lowermost hole, d. Each chamber o is to beprovided with an orifice, e, of discharge, to which a proper faucet maybe applied for 'drawing from said chamber any portion or all of itsliquid contents.

Generally speaking, I intend that each chamber a should be sufficientlylarge to hold half a gallon or more of sirup, and that each chamber cshould be large enough to contain about a pint of sirup, or a quantitysufficient for flavoring a dozen glasses of soda-water. Vithin theice-chamber b there is a closed vessel or hollow cylinder, f, which issupported in place by means of two pipes, g h, of induction andeduction, or it may be otherwise supported, in which. case'it is to havesuch pipes. The induction-pipe g leads into and terminates at the top ofthe vessel f', while the eductionpipe h leads out of the said top andextends into the vessel f and terminates near its bottom, the same beingas shown in Fig. 4. This cylinder is for holding soda-water, which is topass through it in its passage from a sodafountain to the faucet, bywhich it may be drawn into a glass tumbler or other vessel for beingdrank. In consequence of the discharging-pipe of the soda-vessel beingmade to extend into it, gas, while the apparatus may be in use, willaccumulate in the upper part of the soda-vessel and serve to aid indischarging its contents while the faucet of the said discharge-pipe maybe open. It' the ice-chamber be supplied with ice or a refrigeratingmixture and the several chambers a ct a a contain sirups of differentkinds, such as are employed for iiavoring soda-water, such sirups willbe kept in a cool state, fit for being drank, and will be preserved fromfermentation as well as from dust and flies or other insects, the seriesof chambers a a aa, as well as the ice-chamber, being provided with oneor more covers. So, when the sirups are com posed of more or less milkor cream, by my apparatus they will be prevented from becom ing acid. Asthe auxiliary sirup-chambers are at the lower part of the ice-chamberthey will there be subjected to the greatest influence of the coldwithin it, and consequently the sirup in them will more readily becomecold than when in the main sirup-chambers or larger vessels. The twoholes d e, besides performing the functions hereinbefore stated, serveto facilitate the circulation of the sirup in and through the main andauxiliary chambers. A further advantage of the auxiliary Sirup-chamberis that containing a small body of sirup in comparison to that held byits main sirup-chamber, such small body Will be expeditiously cooled bythe ice, and much more so than the sirup of the main chamber, andconsequently, even While the sirup in the main chamber may be nearly atatmospheric temperature, that in the auxiliary chamber Will be reducedto a temperature tit for being drank. By having the soda-cylinder andits pipes applied to the ice-chamber of the sirupcooler We save thenecessity of packing the main soda-fountain in ice or keeping the Wholebody of the soda-Water therein in a cool state for being drank. Thus notonly are sirups prevented from fermenting, by means of my Witnesses:JAMESV W'. TUFTS.
